Active break assist, blind-spot, and ESP all not functioning
Yesterday while driving I got three consecutive error/alert screens stating that the blind spot monitoring, active break assist, and ESP were no longer functioning. I also noticed that the auto/start stop was also no longer active and couldn't be turned back on (although there was no error announcing that). After parking for a store visit, the errors reappeared after restarting and driving for a couple minutes. After parking overnight, a short early AM trip to the gym did NOT trigger the same errors, until 2 ours later when I returned home. So fairly inconsistent. Anyone experienced this trifecta of errors? Have a service visit set-up but not until end of the month unfortunately.
There were few times when I had active break assist "Off" message. Couple of times were during snow storm, when front radar gets covered with snow or ice, and few times it gave me the massage that the front radar is blocked, but when I checked it was just dirt, mud, etc. On all occasions the message went away once the front star got cleared/cleaned.
